The healthcare provider prescribes enoxaparin sodium 80 mg SUBQ twice daily. The nurse is preparing a preloaded 1 mL syringe labeled, 'Enoxaparin sodium injection, USP 60 mg/0.6 mL.' How many mL should the nurse administer? (Enter numeric value only. If rounding is required, round to the nearest tenth.)
Correct Answer: 0.8
Rationale: Desired dose = 80 mg, Concentration = 60 mg/0.6 mL = 100 mg/mL. Volume = 80 mg / 100 mg/mL = 0.8 mL.

When preparing to apply a scheduled fentanyl transdermal patch, the nurse notes that the previously applied patch is intact on the client's upper back and the client denies pain. Which action should the nurse take?
- A. Administer an oral analgesic and evaluate its effectiveness before applying the new patch.
- B. Apply the new patch in a different location after removing the original patch.
- C. Place the patch on the client's shoulder and leave both patches in place for 12 hours.
- D. Remove the patch and consult with the healthcare provider about the client's pain resolution.
Correct Answer: B
Rationale: Fentanyl transdermal patches should be applied to a different location after removing the original patch to ensure consistent pain management while preventing skin irritation or overdose. Administering an oral analgesic is unnecessary if the client has no pain, leaving both patches risks overdose, and consulting the provider is not immediate unless opioid need is reassessed.
The nurse is caring for a client with atrial fibrillation who receives a prescription for warfarin. The international normalized ratio (INR) is 2.8. Which action should the nurse take?
- A. Obtain another blood sample.
- B. Give the next scheduled dose.
- C. Monitor for signs of bleeding.
- D. Notify the healthcare provider.
Correct Answer: C
Rationale: An INR of 2.8 is within the therapeutic range for atrial fibrillation, but monitoring for bleeding is critical as a routine precaution. Repeating the sample, giving the dose, or notifying the provider are less immediate.
When administering zolpidem to an older client, which computer documentation indicates that the desired outcome has been achieved?
- A. Exhibits fewer emotional outbursts.
- B. Improved ability to concentrate.
- C. Decreased episodes of incontinence.
- D. Sleeps soundly through the night.
Correct Answer: D
Rationale: Zolpidem is a sedative for insomnia, and sleeping soundly through the night indicates its effectiveness. Emotional outbursts, concentration, and incontinence are not primary targets of zolpidem.
The nurse is administering SUBQ enoxaparin to a client following knee replacement surgery to prevent a deep vein thrombosis. Which laboratory result requires immediate action by the nurse?
- A. Platelet count of 100,000/mm3 (100 x 10^9/L).
- B. Serum creatinine 1.0 mg/dL (88.4 μmol/L).
- C. Blood urea nitrogen (BUN) 20 mg/dL (7.1 mmol/L).
- D. Hematocrit 45% (0.45 volume fraction).
Correct Answer: A
Rationale: A platelet count of 100,000/mm3 indicates thrombocytopenia, increasing bleeding risk with enoxaparin, requiring immediate action. Creatinine, BUN, and hematocrit are within normal ranges.
The nurse is caring for a client with hypertension, gastroesophageal reflux, and osteoarthritis. While performing a bedside assessment, the nurse observes the client is alert and oriented, but is exhibiting signs of jaundice. The nurse should notify the healthcare provider about which scheduled medication?
- A. Captopril.
- B. Acetaminophen.
- C. Omeprazole.
- D. Prednisone.
Correct Answer: B
Rationale: Acetaminophen can cause liver toxicity, manifesting as jaundice, especially with high doses. Captopril, omeprazole, and prednisone are less commonly associated with jaundice.
